Spear of Mingyingapo (Spear of Cause and Effect) is a divine armament created from materialisation of principle by the Ancient Serenities’ Primal Chaos Will.
Ancient Serenities’ Primal Chaos Will
The wound inflicted by the spear can’t be healed by any normal means.
Song Shuhang used the spear, reshaped into a ghost-headed sabre, together with the karma of seven Eternal Life Being or higher to blast Demon Emperor Hezhi. The demon emperor needs at least several hundred years to recover from that single attack.
